SPECIFICATION forming part of Letters Patent No. 64,9 9. dated January 1, 1901. Application filed December 151 899. Serial No. 740,295. (No model-J To all wh0m it"mdy concern.-

Be it known that I, LOUIS L. CORBETT, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Magazine-Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to firearms in general,and more particularly to that class known as magazine-rifles, one'object of the invention being to provide a lock mechanism which will operate to successively receive the cartridges from the magazine, then plac'e'them in the firing-chamber, then strike the cap, and finally eject the empty shell.

A further object of the invention is to provide a construction in which the entire mechanism may be manipulated to perform its several functions by the operation of a single trigger.

Further objects of the invention are set forth in the following specification.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a side elevation of a magazine-rifle constructed in accordance with the present invention. Fig. 2 is an enlarged detail elevation showing the lock-plate with the mechanism of the lock in its normal position after the cartridge is exploded, a portion of the magazine being in section. Fig. 3is a view similar to Fig. 2 and showing the positions of the parts when the trigger is first drawn to raise a cartridge into line with the bolt and the firing-chamber. Fig. 4is similar to Fig. 2 and showing the position of the parts when the trigger is first released. Fig. 5 isa sectional view showing a portion of the bolt and the extractors carried thereby for drawing the shell from the firing-chamber. Fig.

6 is a view similar to Fig. 5 and showing the positions of the parts when the shell is ejected.

Referring now to the drawings, 10 represents the stock of a gun, and 11 the barrel, and in which stock is mounted a lock carried by a frame 12. This frame is preferably formed integral with the barrel. At the front upper and lower edges of the frame are formed flanges 13, 13'', and 14, respectively, and in the front flange 13, through which the bore of the barrel 11 opens, there opens also the magazine 15, which is of the common tubular form and contains a follower l6, operated by a helical spring 17, which acts to press the cartridges to pass successively from themagazine to the receiving-chamber of the lock.

The receiving-chamber is formed by a passage formed transversely of the inner face of the frame 12 adjacent to the' end flange 13 and separated therefrom by a shoulder 18 A corresponding shoulder 20 is formed on the inner face of the flange 14 at the opposite side of the magazine. Opening therefrom and between -he shoulders is disposed a carrier 21, adapted for vertical reciprocation. This carrier has a curvilinear longitudinal recess in its upper cd ge, one side of which is higher than the other side.

In the frame 12, at the upper end of the receiving-cham her, is formed a discharge-opening 24, through which the empty shells as they are withdrawn from the firing-chamber are discharged.

In the inner face of the flange 13 of the frame is formed a slot 25, which communicates at its forward end with the receiving; chamber and is in alinement with the bore of thegunbarrel. In thisslot is slidably arranged a bolt 26, which is adapted to engage a cartridge after it has been raised by the carrier and force it into the firing-chamber 27.

This bolt also contains a loose longitudinallydisposed firing-pin 28, which projects from both ends of the bolt and is adapted for engagement by a hammer hereinafter described.

In order to reciprocate the bolt 26 and also the carrier, a trigger 29 is pivoted at its upper end to the frame 12 and is held normally in its forward position by means of a V-spring 30, bent upon itself to surround'a screw 31 in the frame, after which its ends 32 and 33 are curved outwardly, the end 33 lying against a stop 34 upon the frame, while "the opposite end engages the trigger below its pivot and above the finger-piece 35, which extends outwardly through the trigger-slot in the gunstock in the usual manner. The trigger has a recess 36 just above the finger-piece 35, and in this recess is disposed one end of a link 37, having a longitudinal slot 38. In this longitudinal slot lies a screw 39, engaged with a perforation in therecess 36*," the head of the screw lying against the opposite face of the link to hold it from outward displacement. Thus it will be seen that as the trigger is 'moved backward a'nd'forward the link will be reciprocated, but that the trigger will have anamo int of lost ,motion with respect to the link. The opposite. end of the link 37 is pivoted to a lever 40, which in turn is pivoted to the frame by means of a screw 41, the upper end of the lever 40 having a link connection 42 with the recess 43 in the bolt 26. when the trigger is drawn rearwardly to the Thus in Fig. 2) with a cartridge resting thereon.-

When the bolt is drawn'rearwardly, the carrier is raised to bring the cartridge in line with the firing-chamber, so that when the bolt is pressed forward it will press the cartridge erate the carrier, a recess 44 isformed in a side face of the lever 40 and lying on both into the firing-chamber. In order to thus opsides of the pivot-screw 41, and in this recess and upon this screw is pivoted a lever 45, the opposite end of'which is pivoted to alink 46, which in turn is pivoted in a slot 47 in the carrier 21. The lever 45 extends slightly beyond its pivot and is adapted for engagement alternately at opposite sides of its pivot by lugs 48 and 49 upon the inner face of the lever 40 and at the lower corners thereof; Thus as the lever. 40 is rocked rearwardly by the backward movement of the trigger the lug 48 will engage the lever 45 and will lift it, and thus raise the carrier. It is of course necessary that the carrier remain raised until after the bolt has engaged the cartridge and started it into the firing-chamber, and for this purpose a fiat spring 50 is provided and which has a projection 51, which is adapted to enter a recess 52 in the lever 45, adjacent its pivot, whenthe lever is in a position to hold the carrier elevated. Thus when the trigger is moved forwardly the carrier does not drop until the lever40 is rocked forwardly to an extent sufficient to engage the lug 49 with the lever 45 and move the notch thereof from engagement with the projection 51 of the spring 50, when further movement of the lever 40 will cause the carrier to move downwardly.

In order to lock the bolt against rearward movement under the influence of the explosion of the cartridge, a finger 55 is pivoted upon the pivot of the trigger 29, and fixed to the trigger is a flat spring 56, the free end of which bears against the rear end of the finger and normally holds it yicldably in position to lie with its free end adjacent the rear end of the breech-bolt. When the trigger is rocl ed through that part of its path in which it has lost motion with respect to the link 40, the .finger is moved from behind the bolt, so that when the trigger is further moved the bolt may be drawn rearwardly, as above described. As .thebolt moves rearwardly theztrigge'r moves the finger downwardly and out of the way. This rearward .movenient of the bolt 26 acts to press the hammerhackwardly and cook it. -When the trigger'is' moved forwardly'to push the bolt forwardly, there is a tendency to raise the finger 55to'i'ts operative position; but as it rests with its free end in this position against theunder side of the boltthe finger is not raised, but the Spring 56 is pressed, sothat when the bolti's-pushed tothe limit of its forward movement the spring acting upon the finger forces its free end up} wardly to engage behind the bolt, as above described. When the trigger is again pulled, it first draws finger 55 down out of the way,

at which time pin 39 reaches the e nd'o'f' slot 36, and continued movement of thetrig'ge1 draws the bolt backwardly.

The hammer'is P nalong tudii ah recess 59 in the frame and whe i it -1 ative position engages the firing-pin in the}? breech-bolt.

A foot 60 is formed upon the lower end of the hammer, and upon this foot y rests one end of a V-shaped spring 66, which,

is disposed in the recess 59 and bears at its opposite end against one wall thereof. The breech-bolt in its rearward movement presses p the hammer rearwardly until its cocking-' notch 60 receives the sear 61, which is piv= oted in the. recess 59 and is held yieldably inthe direction of its operative position by means of a spring 62. The sear 61 has an engaging edge 63 at one end, while its opposite end passes under the trigger 29 and has alate-ral projection 64 lying beyond the rear face of the trigger and in the path of a lug 65 'upon the trigger. This projection is so positioned that as the trigger is initially moved rearwardly and before the finger 55 moves from behind the bolt 26 the lug 65 engagse the- 7 mer, thus allowing the spring66 to throw the hammer against the firing-pin in the bolt 26 d to explode the cartridge.

In Figs. 5 and 6 of the'drawings there is shown a form of shell-ejector in which e'xtractors and 81 are mounted upon opposite sides of the bolt and projecting forwardly thereof to engage the rim of the shell, when the bolt is moved backwardly. These extractor-claws snap over the rim of the shell, and then when the bolt is drawn they draw the shell from the firing-chamber. A springfinger S4 is fixed to the frame 1.2 directly opposite to the opening 24, the free end of the spring-fingerextending in the direction of the firing-chamberand in the path of movement of the shell from the firing-chamber. -When. the bolt is pressed forward, it engages this spring 84 and presses it to one side. When the bolt is drawn rearwardly to extract the shell, the spring 84 falls outwardly and knocks the shell from the fingers 80 and '81 and through the opening 24.
